Jack Flash
Jack Flash probably didn't inspire that classic Stones tune, but it could have! This sh*t is awesome with rockin' Haze highs, blinged-out yields & enough speed to get you to the show on time. The only thing Jack Flash is missing is a few star-struck groupies & a tour bus. It's stellar!

Jumping Jack Flash is Ready in a, Well, Flash ... For a Sativa!

Jack Flash Seeds' 60-70 days might sound like forever compared to Sensi Hash Plant's mere 40 days, but we're talking top-grade Sativa here. Compared to traditional Jack Herer's 12 weeks or more, this is a real speed demon!

So how did Sensi Seeds ramp these babies up? Jack Flash is the direct result of generations of selective crossing, back-crossing & inbreeding using Sensi Seeds Jack Herer, a premium Super Skunk & a rare pure Haze. Not only are these cannabis seeds faster, they're bulkier too.

  • Jack Flash Adds Bulk & Speed to Classic Jack Herer
  • 2 Possible Phenos - Indica or Sativa Leans
  • Impressive Yields Either Way - They're Both Keepers!
  • Priced to Please & Ready to Ship!

Best of all, Jack Flash Cannabis Seeds didn't lose a bit of original Jack's distinctive high. It's a win-win on all accounts!

Sensi Seeds Jack Flash reduced Jack's 4 possible phenotypes to just 2. Depending on the luck of the draw, your new marijuana seeds could be SOG-sized Indicas with stack after stack of resin-swollen buds or tall, classic Sativas with unparalleled flavour, effects & delectable runs of Skunk/Haze bud. Another win-win!

If you're a Jack Herer fan, you have to buy Jack Flash Cannabis Seeds. This incredible hybrid throws in just enough Super Skunk to add a little bulk & speed to this bad-ass strain up without compromising the luscious Haze. In The Rhino's opinion, it's even better than the original Jack!

If you're a lucky UK'r, you can legally buy Jack Flash for your dormant cannabis seed collection, but germination, cultivation & growing is still strictly illegal. For more on this sensitive subject, please read the Rhino Seeds' disclaimer page.
